Application filed May 9, 1908. Serial No. 431,739.

To all whom it may concern Be it known that I, RALPH R. Roo'r, a citizenof the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented a certain new and useful Improvement inBrooders, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings. Myinvention relates to broodersand has for its object the provision of abrooder of the type known as the shelf brooder.

This brooder is adapted to be usedv 1ndoors, being placed upon a shelf,as 1s customary, a large number of the indivldu'al brooders are housedin the same quarters.

The construction of the'brooder is such as to allowa free passage of airthrough the same which greatly improves the sanitary condition of thebrooder and the health of the chickens. v I

Generally speaking, the invention con1 prises the elements andcombinations thereof set forth in the claims.

Reference should be had to the accompanying drawings in which Figure 1is a central longitudinal section of the brooder. Fig. 2 is a. centrallongitudinal section of the improved water heater. Fig. 3 is atransverse longitudinal section of the water heater on the line 00 a ofFig.2. Fig. 4 is a perspective show ng the water heating drumand theradiatmg tubes.

The brooder comprises'a frame generally represented at l, which framesupports, in a manner to form the sides: thereof, auxiliary frames '2which are covered with w re netting. These frames are adapted to engagethe sides of the main frame 1 and are held in place by any.suitable'means. The wirenetting is held in place by any desired meansand allows'the free circulation of the air through the'brooder. V

Within the main compartment is a swinging platform 3 which is adapted tobe suspended by four chains 4 that are secured to the frame 1 by meansof projecting pins which are secured upon the outside of the frame 1 andengage alink upon each of the chains, thereby supporting the platform 3.

The platform itself is supported upon two transverse members 4E,one ofthe said members being located near each end of the plat form. ,Thesemembers are at each oftheir Fig. 5 is a perspective view. of therespective ends secured to one of the chains 4. It will thus be seenthat the platform 3 may be supported in any desired position between thetop and .bottom of the brooder by-placing the-desired links ofthech'ains in engagement'with the pins; In this manner the distancebetween the platform 3.and the tubes .canvbe varied to accommodate thechicks as they grow. 7 .2

1 Near the forward end of the brooder isa slanting. platform 5 which isin proximity to the end of the platform 3, so that the chicksmayclimbjover the end of the plat-- form. and down the incline 5 toa'running space. 1 r

The heating device which is housed in the rear portionof the brooder terheating drum 6 which tubes 7 projecting from it, which tubes slantslightly in an upward direction so that a comprises a wahas a series ofcirculation ofsthe heated water may be obtained. fromythe. drum throughthe tubes. Thesetubes are secured tolthe heating drum 6 in a suitablemanner. The interior of the drum and tubes are in communication witheach other, while the outer 'endsof the tubes are closed; The tubes attheirflouter ends are held inproper relative position by? means of anangle bar 8 to which they are suitably secured. The heatingdrum andpipes are suitably supported within the'brooder by a plate vmember 9which extends from wall to wall of the brooder and at a suificientheight above the bottom thereof so that the outer end of the pipes 7will extend nearly to the top of the frame. heater '6 engages with thesurface of the plate9 and the end walls of the heater 6 en= gage withthe side walls of the: brooder near frame which hook engages with theangle iron 8. Above the tubes is a frame 10 which is covered withwirenetting the sameas are the side frames 2. This member is of a sizeThe inner wall of the 1 its rear end. The drums and tubesareheld inplace by a hook. 8 secured. in the main to just fit the top portion ofthe brooder, and

is supported by resting upon the tubes and heater drum. This nettingwill prevent the chicks from piling one upon another, be cause they willnot be able to get above the tubes.

The-heating drum is formed of sheet metal and comprises a top member 11and depending side members 12 andend members l3. Thebottom of the heateris formed by a piece of sheet .metall4 spaced a short 1" distance fromthe top which is of less area than the top and is connected to the sides12; and 13 by means of slanting members 15 and 16. The formation of theheater thus provides a chamber inclosed by the sides 15' and 16 withinwhich a certain volume of heated air is retained so as to supply theheat to the water within the drum.

An auxiliary drum 17 is supported from the drum 6 by means of a verticalpipe 18 and an obliquely slanting pipe 19. The pipe 19 is connected withthe heating drum 6 at a point near the lower part of one of the endwalls 16. ,The drum 17 is formed with a central opening 20 into whichthe burner of the lamp isadapted to project. Any desired means ofheating the drum 6 may be employed. However, I have shown an oil lamp toperform that function. The lamp, as shown, is of ordinary constructionhaving an elongated body portion 27, a burner 28 which is adapted toproject into the opening 20 inthedrum-17, and a flexible spring 29engaging the bottom. By means of this spring the burner of the lamp isheld in contact with the drum 17 atlall times when the heating apparatusis in position in the brooder.

' heating of the burner.

Due to the fact that the pipe 19 is in communication with the drum 6near the lower portion thereof, the cooler water in the drum .6 willpassthroughthe pipe 19 to the druml17 and thence as it becomes heated, willpass upwardly through the pipe 18 and return-again into the drum 6. Thiswill secure a' circulation of the coldest water through'the drum 16whichwillat all times keep the burner cool and prevent the over- A sighttube 21 is provided, which projects through the top and bottom of thedrum 6 in a slanting direction, and is so placed that the eye ofanobserver may see the flame'of the lamp by looking through the same andthus obviating the necessity of the removal of thelampwhen it is desiredto inspect the condition of the flame.

. The outer end of this tube is closed by a cap'22 which may be formedof any suitable material preferably of a transparent material which willnot be affected by the heat, such as mica. l

Asecond tube 23 projects through the top and bottom of the drum 6' nearone end thereof, and extends below the bottom 14: a distance midwaybetween the bottom 1&

, and the lower extremity of the sides 12. This construction providesthat a body of heated airwill always be in contact with the bottom 14 ofthe drum. Above the top of the drum 11 this pipe is formedlwith anelbowand a straight P119624: is sleeved upon the upper portion of the elbow.The pipe 24; is provided with a shield extending across its outer end.The pipe 23 will conduct away the products of combustion, and by virtueof the shield 25 at the outer end of the pipe, the air currents, whichwould tend to enter the pipe 24 and carry the fumes to the spaceoccupied by the chickens, are prevented from entering.

'A cover 26 is provided, which forms a closure for the lower part of theheating from escaping into the part of the brooder occupied by thechickens.

q The drum 6'is provided with a capped opening 26 which allows thefilling of the tank with water.

. The operation of the device which I have described is as follows: Tank6 is provided with a suitable amount of water and the burner is placedin position beneath the same so that the burnerof the lamp will engagewith the walls of the passage 20 in the drum 17. :As' thewater becomesheated, it will tend to circulate through the tubes 7 and so supply heatto the chicks which are contained within the brooder. Upon the return ofthe water from the pipes 7 to the drum 6, the cooler water will sinktoward the lower portion of the drum 6 and will circulate through thepipes'7.

from catching on fire. Again, practically all the heat supplied by theburner is saved, for the heat absorbed due to the cooling of the burneris given to the water in the main drum, and thus practically all theheat developed is utilized; but what is thexmost practical of theadvantages, the quantity'of oil consumed by thelamp under theseconditions is materially reduced, for the reason that substantially allthe heat is saved and utilized. Consequently, the lamp does not have tobe forced to supply heat andso the quantity of oil consumed will beless.

The provision of the removable sides is of great'advantage in that thetrayB can be removed and cleaned very quickly and easily and by virtueof thewfact that the sides are composed of wire netting, the air maycirculatefreely through the brooder which will keep the chicks in ahealthy condition.
